GZMB gene silencing confers protection against synovial tissue hyperplasia and articular cartilage tissue injury in rheumatoid arthritis through the MAPK signaling pathway

Taken together, the key findings of the present study ultimately suggest that GZMB gene silencing acts to inhibit MAPK signaling pathway through regulating the expressions of inflammatory factors, factors correlated with apoptosis (bcl-2 and caspase), as well as factors associated with angiogenesis (VEGF and bFGF), thus relieving synovial tissue hyperplasia and articular cartilage tissue injury brought about by RA. The GZMB gene could well be a new therapeutic target for RA treatment.
